Gütermann | 重型/頂針線 | 30 公尺 | #511 | 淺棕色

Used this heavy duty thread for the topstitching on a pair of jeans, and it held up perfectly through the machine without any fraying. The light brown color matched my denim nicely, and the thread stayed supple even after multiple passes. Really glad it didn't snap under tension.

The silk-like lustre really makes the topstitching pop on my denim projects, and the thread stays soft and pliable even after multiple passes. This spool handled a thick canvas bag seam without snapping once, which is more than I can say for my usual threads.

The stitching on a denim repair came out really clean and the silk-like shine gives it a nice finish for topstitching. It's a bit pricey for 30 meters, but the strength feels worth it for heavy projects.
